PROBLEM TO BE SOLVED: To enable an urea selective catalytic reduction device to remove nitrogen oxide in exhaust gas discharged from a DPF unit.SOLUTION: A combine-harvester comprises: an urea selective catalytic reduction device (70) which is disposed above a DPF unit (40) and removes nitrogen oxide in exhaust gas after passing through the DPF unit (40); an exhaust gas inlet port of the DPF unit (40) which is connected through a connection pipe (50) to an exhaust manifold (30B) of an engine (9); an exhaust gas outlet port of the DPF unit (40) which is connected through a connection pipe (73) to an exhaust gas inlet port of the urea selective catalytic reduction device (70); a tail pipe (61) which is connected to an exhaust gas outlet port of the urea selective catalytic reduction device (70) and discharges the nitrogen oxide -removed exhaust gas to the outside; and a cover (62) of double structure including an inner cover (62A) and an outer cover (62B) which is mounted in an exhaust port of the tail pipe (61).SELECTED DRAWING: Figure 9

    【課題】尿素選択触媒還元装置によって、DPFユニットから排出される排気ガス中の窒素酸化物を浄化できるものとする。【解決手段】DPFユニット(40)の上側に、DPFユニット(40)通過後の排気ガス中の窒素酸化物を浄化する尿素選択触媒還元装置(70)を配置し、DPFユニット(40)の排気ガス流入口を、接続管(50)を介してエンジン(9)の排気マニホールド(30B)に接続し、DPFユニット(40)の排気ガス流出口を、連結管(73)を介して尿素選択触媒還元装置(70)の排気ガス流入口に接続し、尿素選択触媒還元装置(70)の排気ガス流出口に、浄化後の排気ガスを機外へ排出するテールパイプ(61)を接続し、テールパイプ(61)の排気口に、内側カバー(62A)と外側カバー(62B)を有した2重構造のカバー(62)を装着する。【選択図】図9
